HIDE-WORKING- MACHINE.

Specification of Letters Patent.

Patented July 2, 1907.

To all whom it may concern:

Be it known that we, Or'ro E. BECK and EINAR J. BECK, both citizens of the United States, and residents of Racine, in the county of Racine and State of Wisconsin, have invented certain new and useful Improvements in Hide-Working Machines; and we do hereby declare that the following is a full, clear, and exact description thereof.

Our invention consists in what is herein shown, described and claimed;. its object being to provide-simple, economical and efiicient machines for unhairing and fleshing hides, particular reference being had to the detail of the unhairing mechanism the operation of which simulates hand work.

Figure l of the accompanying drawings represents a side elevation of the major portion of a machine in accordance with our invention having portions thereof broken away and in section; Fig. 2, a plan view of the machine partly broken away and in section, as indicated by line 2-2 in Fig. 1; Fig. 3, a sectional view of a fragment of the machine on the plane indicated by line 33 in Fig. 4, and Figs. 4 and 5 similar views respectively indicated by lines 4-4 and 5-5 in Fig. 3.

Referring by letter to the drawings, A indicates one of a pair of standards of our improved machine, which standards areprovided withJoearings for the shaft B of the hide-drum O, as is common in the art, and the drum is rotated in opposite directions at will, accordingly as the machine is used for unhairing or fleshing operations, one direction being indicated by arrows in Figs. 1 and 2 at which time the fleshing-mechanism is idle.

In pivotal connection with each standard of the machine is an arm D provided with bearings for the journals of a fleshingcylinder E, a link-rod F in connection with the arm being for attachment to a treadlemechanism. A stop-screw b is adjustable in connection with the standard to regulate descent of the aforesaid arm and cylinder.

Each standard of the machine is provided with inclined slots 0, that serve as guides for blocks G to which a knife-plate H "is bolted, and likewise connected to the blocks are the ends of a yoke I hung from an arm I having an angular lug d for which guides d are provided in connection with said standard. Hung from the standard is a spiral-spring K attached to the lug of the arm J, and a link L is suitably connected at its ends to said arm and a lever M, which lever is fulcrumed in connection with said standard, a link-rod N attached to said lever being for connection with a treadle-mechanism.

The knife-plate H is provided upon its under side with a series of pintle-lugs 0 arranged in pairs, certain of which pairs are stepped from the center of said plate toward opposite ends of the same in echelon. Hung on the pintle lugs of the plate H are eye-lugs f of swing-hangers O to which knives P are bolted or otherwise suitably fastened, provision being had for adjustable set of said knives in connection with said holders. Coupled by a bolt g to back-ears h of each knife-hanger is a rod Q having a flange i that supports a spiral-spring j, and said rod extends through a transverse slot of the plate Hand an eye of a block R trunnioned in a box-frame S adjustably held in guides is provided on said plate. Run on the screw-threaded outer end of each rod Q, against the corresponding swivel-block R, is a nut m, and a clamp-screw T extends through a clamp-bar U into the box-frame for said block, this bar being crossed on the block-guides.

By means of the clamp-screws and bars the several box-frames S are held in adjusted position, the same determining the normal angle of the knives, the nuts m on the rods Q having been previously adjusted to regulate the tension of the springs j, said knives being preferably of sufllcient width to provide for overlapping of the same in echelon, as shown in Fig. 2. The knives being independently adjustable, as to angle with respect to the hide-drum O and plate H, they are readily set to conform to varying thickness of the respective hides upon which they operate, and when brought into action upon a hide, by a downward movement of said plate against retracting spring resistance, there is an even scrape on the entire surface of said hide, the springs aforesaid permitting automatic yield of said knives to conform to irregularities of such surface. The knives being disposed as above described, the hide is stretched upon the drum C evenly in opposite directions, as a result of the action of said knives thereon, and each knife scraping independently of the others, the action of a hand unhairing-knife upon a hide laid on a beam is simulated, this being a desirable result and'an especial feature of our invention. To limit downward movement of the knife-plate H, stopscrews n are provided in connection with each stand-- ard of the machine to oppose the blocks G aforesaid.

We claim:

1. A hide-working machine comprising a rotary hidedrum, a reciprocative plate transverselyslotted at intervals longitudinally thereof, a series of knife-holders in independent pivotal suspension from the plate opposite the drum, eye-blocks arranged in connection with the plate in register with the slots of same, rods engaging the blocks and pivotally connected to the knife-holders, and-a tension-spring on each rod between the companion knifeholder and block.

2. A hide-working machine comprising a rotary hidedrum', a reciprocative plate transversely slotted at intervals longitudinally thereof, a series of knife-holders in pivotal suspension from the plate opposite the drum, eyeblocks arranged in connection with the plate in.register with the slots of same, rods engaging the blocks and pivotally connected to the knife-holders, a tensionspring on each rod between the companion knife-holder and block, and a tension'nut run on the rod in opposition to the outer side of the opposing block.

3. A hide-working machine comprising a rotary hidedrum, a reciprocative plate transversely slotted at intervals longitudinally thereof, a series of knife-holders in inclepedent pivotal suspension from the plate opposite the drum, a corresponding series of box-frames adjustable on said plate in register with the slots of same, a block trunnioned in each frame, a rod loose in an eye of each block and pivotally connected to a knife-holder, a tension-spring on each rod opposing one side of the corresponding block, and a nut run on said rod against the opposite side of said 10 block.

In testimony that we claim the foregoing we have hereunto set our hands at Milwaukee, in 'the county of Milwaukee and State of Wisconsin, in the persenee of two witnesses.
